  An NMR Study of Halogenated 1,4-Dihydro-1-ethyl-4-oxoquinoline-3-carboxylates

  摘要：

  Ethyl 1,4-dihydro-1-ethyl-4-oxoquinoline-3-carboxylate and 29 of its mono-, di- and tri-fluoro and/or -chloro derivatives were synthesized and their H-1, C-13 and F-19 NMR spectra were recorded. H-1,C-13 and F-19 chemical shifts, J(HH), J(FH), J(CF) and J(FF) coupling constants are reported. The C-13 substituent chemical shift values of the chloro and fluoro substituents were calculated by linear multiple regression.

  Nipah virus (NiV), a highly pathogenic paramyxovirus. causes respiratory disease in pigs and severe febrile encephalitis in humans with high mortality rates. On the basis of the structural similarity of viral fusion (F) proteins within the family Paramyxoviridae, we designed and tested 18 quinolone derivatives in a NiV and measles virus (MV) envelope protein-based fusion assay beside evaluation of cytotoxicity. We found five compounds successfully inhibiting NiV envelope protein-induced cell fusion. The most active molecules (19 and 20), which also inhibit the syncytium formation induced by infectious NiV and show a low cytotoxicity in Vero cells, represent a promising lead quinolone-type compound structure. Molecular modeling indicated that compound 19 fits well into a particular protein cavity present on the NiV F protein that is important for the fusion process.
